Motivation

...

Current implementation of ZookeeperDiscoverySpi should be rewritten, because Zookeeper and similar coordinators (i.e. etcd) are not intended to store large amount of data.

TCP transport for delivering messages should be implemented and leave Zookeeper only coordination, service  service discovery and similar tasks.

Integration testing framework

Local checks provide non-relevant results. Real cluster checks may be non-reproducible.

To develop, check and be able to recheck fixes related to "Crash recovery speed-up" we should write a framework that allows us to create reproducible tests that can be performed in a real environment. 

A possible solution is to use the Ducktape framework.

Forked to IEP-56: Distributed environment tests.
